In a manufacturing process, 0.2% of the brake pads that come off the production line are considered defective. determine the probability that at least one brake pad is defective in an order of 200 pads

Step-by-step explanation:

Given: The probability of brake pads that come off the production line are considered defective. = 0.2

Therefore, the probability that the brake pads are not defective=1-0.2=0.8

The probability that all 200 pads are not defective P(all 200 non defective)=

Then the probability that at least one brake pad is defective in an order of 200 pads

P(at least one defective)=1-P(all 200 non defective)

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
